BEARING.

T 0 all whom it may concern.

Be it known that I, Jnssn C. WELOH, a citizen of the United States, and resident of Tacoma, county of Pierce, State of Washington, have invented certain new and useful improvements in Bearings, of which the following is a specification.

This invention relates to new and useful improvements in bearings, and the object of this improvement is to provide a bearing of a compound form of construction comprising a plurality of co-acting units to compensate for the vertical and lateral pressures as may be applied thereto.

A further object resides in the provision of a bearing that will greatly reduce friction from the surfaces of rolling contact where the pressures are laterally applied, hence reducing excessive wear upon these rolling surfaces.

The invention consists in the arrangement, construction and combination of parts, as will be more fully described in the following specifications, illustrated in the accompanying drawings and finally pointed out in the appended claims.

In the drawings:

Figure l. is a view in side elevation of my compound bearing as applied to a wheel structure.

Fig. 2 is a vertical section of the same.

Fig. 3 is a vertical section of an alternatively form of construction.

Fig. 4E is a plan view of the hearings in assembled position.

Referring more particularly to the draw inns, in which like reference numerals indicate like parts. the numeral 1 represents a stationary member provided WlLll a continuous raceway 2 around its outer periphcry for the reception of the bearing to illustrat the application thereof.

This bearing consists of a roller 3 hav-- ing a hub 5 at its axis. as shown in Fiq. 2, the hub being preferably provided with a plurality of socke s on its respective ends for the reception of balls 6.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed April 2, 1919. Serial No. 286,906.

within sockets provided in the housing 9 that laterally incases the bearing constituting one of a series of unit structures that are preferably placed around the periphery of the member 1, in spaced apart relation, and are connected together by links 10.

The hearing as shown in Fig. 3 differentiates from the bearing, as described, in one particular only in that the roller 3 can be spherically shaped with the hubs eliminated therefrom.

A bearing of this compound form construction is particularly applicable for sustaining forces of vertical and lateral pressures rotatably applied with a minimum of frictional resistance, as for instance, in its application to the construction as herein shown it is obvious that vertical pressure applied to the rim 11, which is rotatably disposed thereupon, will exert a thrust upon the roller 3, and the lateral and other pressures applied to the rim at an inclination from the vertical will exert a thrust upon the rollers 7, which, being disposed in rolling contact upon the roller 3 is rotatably actuated with respect thereto, hence reducing friction by yielding under the thrust and communicating the lateral pressures to the other co-acting parts to be borne equally thereby.

What I claim as new and desire to protect by Letters Patent is:

1. The combination with complementary bearing members, each having a central raceway and concentrically curved bearing surfaces at opposite sides thereof. ofa bearine' 'comnrisine: a central roller operable with n he cen ral racewavs and paired s de memb rs operable upon the central roller and having con entrically curved rolling surfaces en aeeable with the said concen ricallv curved surfa es in the complementary m mbers on any lateral movement of the latter.

2. The combination with complementary bearing members, each having a central raceway and concentrically curved bearing surfaces at opposite sides thereof, of a bearina' comprising a central roller operable within the central raceways outwardly disposed members at opposite sides of the central roller having concentric rolling surfaces engageable with the concentrically curved surfaces of the complementary members on any lateral movement of the latter, balls interposed between the central and side members and means for sustaining said members in functional position.

3. The combination With complementary bearing members each having a central race- Way and concentrically curved bearing surfaces at opposite sides thereof, of a bearing comprising a central roller operable Within surfacesof the complementary members on any lateral movement of the latter, balls interposed between the central and side mem bers, acage'for-fs aid bearing members and ball pivot at each side of the bearing located J'Essr; c.
